NAT 3 + Disabled Party Chat

Hey guys, I'm having a bit of trouble setting up my internet on the PS4 (not due to PSN being down, although that is a bummer).

Is anyone else experiencing not being able to chat in a party due to having NAT 3? It seems a little extreme to not allow this while I have no other issues playing online. Just wondering if this was widespread/fixable. I've spent all afternoon trying to forward ports and put my PS4 in a DMZ but all this does is make the PS4 unable to connect to the internet and PSN.
